(LaTeX) Abstract:

In this paper, a new free-form shape deformation approach is proposed. We combine a skeleton-based mesh de-
formation technique with discrete differential coordinates in order to create natural-looking global shape defor-
mations. Given a triangle mesh, we first extract a skeletal mesh, a two-sided Voronoi-based approximation of the
medial axis. Next the skeletal mesh is modified by free-form deformations. Then a desired global shape deforma-
tion is obtained by reconstructing the shape corresponding to the deformed skeletal mesh. The reconstruction is
based on using discrete differential coordinates. Our method preserves fine geometric details and original shape
thickness because of using discrete differential coordinates and skeleton-based deformations. We also develop
a new mesh evolution technique which allow us to eliminate possible global and local self-intersections of the
deformed mesh while preserving fine geometric details. Finally, we present a multi-resolution version of our ap-
proach in order to simplify and accelerate the deformation process. In addition, interesting links between the
proposed free-form shape deformation technique and classical and modern results in the differential geometry of
sphere congruences are established and discussed.
